Krystal tinsels like SemperFlash Krystal are standard in most fly tyers materials boxes.
 
With SemperFlash Krystal you get 10” / 25cm long hanks tied at the top rather than center tied tinsels meaning that you can produce really long wings on flies for saltwater or large predators.
 
There are 300 strands of this beautiful SemperFlash Krystal in each pack which is such great value.
 
With full useable length of 10” strands these can be used to create flies from the smallest chironomid/buzzer breathers to huge Tarpon or Muskie flies using the full 10” length of this amazing SemperFlash Krystal winging material
